The Best New Science Fiction Short Stories

Science fiction. The term often conjures up images of epic space battles, time travel hijinks, and daring rescues in rocket ships. And while there certainly are plenty of science fiction short stories like that, the genre offers a level of variety that is, well, out of this world!

Whether they're about a young man who suddenly doubles his IQ or a linguist who encounters an alien species, science fiction stories use extraordinary scenarios to peel back the masks humanity tries to hide behind. They extrapolate the many terrifying and wondrous ways the future could go, all while answering essential questions about humanity. And... they’re thrilling adventures with space lasers and rocketships. 

In short, no subject is too serious or too escapist for this far-reaching genre. From Ray Bradbury to N.K. Jemison and more, science fiction short stories have been an essential part of the literary landscape for decades.
